PHILADELPHIA — Dean Ambrose provided a key assist in helping Seth Rollins advance over Drew McIntyre to a slot in the WWE World Cup — a development that should have put to rest any question of whether The Lunatic Fringe is still all in on The Shield, except the aftermath of Ambrose’s interference left Rollins and Roman Reigns with more questions than answers as to where their brother’s head is at these days.

It's not that Ambrose was conspicuously absent for the pre-match confrontation between Rollins, Reigns and Braun Strowman, Dolph Ziggler & McIntyre — the “pack” that has tormented them over the past couple of months and handed Ambrose the deciding, demoralizing pinfall in last week’s main event. Rollins knew Ambrose would show up when it mattered, and he did, though he waited until the last possible minute to do so (Ziggler had interfered several times from ringside), instigating a scramble outside the ring that led to a narrow count-out victory for The Kingslayer after he hit McIntyre with a Stomp on the arena floor.

Rather, any questions about The Shield's unity will likely stem from their interaction after the match in the backstage area, where Rollins gently razzed Ambrose for his down-to-the-wire timing. “Lunatic time,” Rollins called it, but Ambrose didn’t take it as a term of affection. The former WWE Champion lashed out at his brothers over the implication that he was only good for a laugh until they needed bailing out before walking off to prepare for his own qualifier against Ziggler, alone.
